Wisconsin Mount Pleasant physical buildout cluster

Mount Pleasant has C12 phased construction evidence.

Executive summary

Read the conclusion before the archive.

  1. Mount Pleasant has C12 phased construction evidence.
  2. The verified path stops at C12; the next transition remains bounded by the public record.
  3. No conversion of construction or capex into energized/operating/economic capacity.

01 · Case brief

Why this mechanism belongs in the portfolio.

Physical construction and phased delivery without operating-state inflation. The cluster is retained for its evidentiary function, not as a representative sample or ranking.

01

Observed mechanism

Mount Pleasant has C12 phased construction evidence.

02

Unverified transition

Electrical delivery; energization; commissioning; IT installation; workload; C20

03

Quantitative basis

No normalized public power quantity

Figures remain attached to their stated unit and state basis.

Decision boundary

The evidence ceiling

Permitted conclusion

Phased construction is documented; no C14+ evidence.

Prohibited stronger claim

No conversion of construction or capex into energized/operating/economic capacity.

Quantitative ceiling
No normalized public power quantity
Causal ceiling
No construction-delay cause or outcome claim

02 · Institutional control

The outcome depends on a distributed permission stack.

No actor, filing or contract is allowed to stand in for the entire conversion chain.

Alternative explanations that materially narrow the claim.

A rival “win” does not reverse the record. It defines the strongest inference that survives the contrary evidence.

Contrary evidence and competing mechanisms

CTR-0033 · Demand-quality problem

Construction does not establish commissioning, utilization or economic capacity.

Evidence result:Mount Pleasant and Vantage remain C12 despite extensive public project records.

Ceiling effect:C12 ceiling retained.

CTR-0034 · Policy and data uncertainty

Drafts, work sessions and pending phases are not effective law.

Evidence result:DCOZOD, Hillsboro work session and Loudoun Phase 2 remain process states.

Ceiling effect:No legal-effect claim.

CTR-0035 · Measurement boundary

Site counts, acres and water figures do not measure operating compute.

Evidence result:Hillsboro and Vantage records use non-power units and mixed states.

Ceiling effect:No MW conversion.

CTR-0036 · Adaptation/pathway response

Grandfathering, SPEX and replacement processes can preserve project options.

Evidence result:Local rules change pathways without proving approval or cancellation.

Ceiling effect:No permanent-failure claim.

CTR-0037 · Local-benefit case

Agreements and incentives can include valuation, investment and compliance obligations.

Evidence result:Mount Pleasant and Hillsboro records preserve benefit mechanisms while net outcomes remain unknown.

Ceiling effect:No net-benefit conclusion.

CTR-0038 · Sole-cause thesis

Public local records do not isolate one permission layer as the sole cause of delay or outcome.

Evidence result:Multiple permissions and physical stages coexist.

Ceiling effect:Mechanism-level claim only.

06 · Record maintenance

What would justify reopening this report.

Updates require a documented evidence delta. Passage of time, repetition of an announcement or a portfolio-level disclosure is not enough.

What could change this record

  • OIR-0019 · Any bounded project receives a material cancellation, downsizing, land/permit decision, construction milestone, service agreement, energization, commissioning, phase redefinition, or portfolio-capacity reconciliation.

    Required update: Create dated state observation; preserve prior state; record supersession/overlap; update affected capacity fields without borrowing later-state language.

  • OIR-0033 · Final appellate disposition or replacement approval changes Digital Gateway legal state.

    Required update: Inspect controlling court/local record and update legal and physical states separately.

  • OIR-0034 · Prince William adopts, revises, rejects or pauses DCOZOD text initiated by Resolution 26-374.

    Required update: Inspect final ordinance/resolution; do not carry draft language as law.

  • OIR-0035 · Loudoun Phase 2, grandfathering application or electrical-infrastructure action materially changes a project pathway.

    Required update: Update framework and project-specific effects separately.

  • OIR-0036 · Hillsboro adopts policy changes or publishes materially revised site/water/wastewater data.

    Required update: Preserve boundaries and state labels.

  • OIR-0037 · Microsoft Mount Pleasant receives final material permits, energizes, commissions or changes phase state.

    Required update: Verify each C12–C17 transition independently.

  • OIR-0038 · Vantage Lighthouse receives occupancy/commissioning evidence or material permit/service change.

    Required update: Update permission, energization, commissioning and operating states separately.

  • OIR-0039 · Complete controlling Hillsboro Enterprise Zone and site-specific fiscal outcome records become public.

    Required update: Normalize award, realized benefit, obligations, clawbacks and outcomes.
